IMPROVEMENT IN HEATERS FOR DESKS AND SEATS.

Specification forming part of Letters Patent No. 198,351, dated December 18, 1877 application filed June 12, 1877.

To all whom it may concern:

Be it known that I, MAncELLUs W. CnAsE, of Buffalo, Erie county, New York, have invented Improvements in Heating School- Rooms, of which the following is a specification:

The object of my invention is to uniformly heat school-rooms and similar places, and t0 utilize the heating-pipes as supports for the desks, seats, 85e.; and this I effect by the system of heating-pipes fully described hereinafter, and illustrated in the accompanying drawings, in which- Figure l is a diagram of part of a schoolroom, illustrating my invention. Fig. 2 is a front view, showing the fronts of two desks and attachments; Fig. 3, a side elevation of Fig. 2; Fig. 4, a detached sectional view, enlarged, and Fig. 5 a modication.

Itis well known that the usual systems of heating by radiators generally resultin an unequal temperature, those portions distant from the radiators being unduly heated, or the more distant parts being maintained at too low a temperature.

Where there are a number of available spacesV on the floor of a room, the arrangement of radiators at such points will, in a degree, correct this difficulty; but this cannot be done in school-rooms, churches, theaters, &c., where the seats, desks, or pews occupy all the avail-l able space.

My invention, which effectually remedies this difficulty, consists in a system of heatingpipes, or their equivalents, comprising the supply and waste pipes and hollow supports extending vertically from the supply and waste pipes at various points throughout the entire eXtent of the room, which will therefore be uniformly heated at all points without the ne- It will be apparent that various modes of arranging the pipes and of constructing them to furnish the desired amount of radiatingsurface and the supports of the proper character may be employed. rThe system and construction which I have found most available is illustrated in the drawing, in which- A represents the supply, and A the waste 0r exhaust, pipe, properly inclined to insure the iiow of the drip, and B the connectingpipes, all arranged, preferably, below the iioor. C O are the desks, and a a are tubular supports, which extend above the oor to form continuations of, or connect with, the pipes B, serving to sustain the desks, seats, &c., and constituting the radiators, by which the room is heated uniformly throughout.

The pipes a may be of the inverted U shape shown in Figs. 1 and 2, their ends communicating with the pipes B, as shown; and where sufficient radiating-surface is afforded by reducing the height, posts b may extend from the pipes a upward to the levelof the bottoms of the desks, which may be further braced by supplementary supports E.

In order to effect a secure attachment to the floor the pipes a may be threaded at the ends, and supplied with fiat nuts or washers c, which may be adjusted to aord a rm bearing, however irregular the 'licor may be, and are perforated or notched for the passage of screws or staples b', to secure the whole in place. In order to deiiect the heat and throw it forward or sidewise, inclined plates s may be suitably arranged beneath the desks.

In some instances it is desirable to arrange the pipes B in a different position, so as not to interfere with the spaces at the fronts of the.

desks. In such cases the side standards are utilized, as shown in Fig. 5, which illustrates a simple and cheap construction, consisting of bent pipes d d and T-couplings, connected by a cross-pipe, f, combined, forming a hollow standard of great strength, but light in weight.

lf desired, the uprights a may be utilized for the support of the seats T, as shown in Fig. 1, or for supporting seats in churches and theaters, and desks in bank buildings, warehouses, and stores, &c.

It will be apparent that steam, water, or air may be employed as the heating medium.

Without limiting myself to any special construction of the hollow supports or to the described arrangement of supply and waste pipes,

I claim- 1. The combination of the supply and exhaust pipes of a heater and a series of hollow pipes or standards, communicating with the heating-pipes, and adapted to support or form the standards of articles of furniture, substantially as set forth.

2. The arrangement, Within a room to be heated, of vertical hollow standards, communicating with the heating-pipes, and constructed to constitute the standards of desks, seats, Ste., as specified.

3. The deilectors s, combined with the desks and heating-supports, as set forth.

4. The standards a, threaded and provided with nuts c, for the purpose specified.

5. The combination, with the pipes d d, T- couplings, and cross-pipes f, forming a hollow radiating-standard, and constructed to support a desk or other article of furniture, as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
